Unity Linux 20.1070a Security Update: kernel (UTSA-2025-986396)

medium Nessus Plugin ID 268146

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986396 advisory.

In the Linux kernel, the following vulnerability has been resolved:

udf: Fix preallocation discarding at indirect extent boundary

When preallocation extent is the first one in the extent block, the code would corrupt extent tree header instead. Fix the problem and use udf_delete_aext() for deleting extent to avoid some code duplication.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
